我在我的应用中使用Adview。但每当我运行应用程序崩溃并显示以下异常时。在激活屏幕之后,MainActivity.java是第一个屏幕。
引起:java.lang.IllegalStateException:广告尺寸和广告单元ID 必须在调用loadAd之前设置。

MainActivity.java
AdView ad = (AdView)findViewById(R.id.adView_Category);
AdRequest adRequest = new AdRequest.Builder()
.addTestDevice(AdRequest.DEVICE_ID_EMULATOR).build();
ad.setAdListener(new AdListener() {
@Override
public void onAdLoaded() {
}
@Override
public void onAdClosed() {
Toast.makeText(getApplicationContext(), "Ad is closed!", Toast.LENGTH_SHORT).show();
}
@Override

Toast.makeText(getApplicationContext(), "Ad failed to load! error code: " + errorCode, Toast.LENGTH_SHORT).show();

Toast.makeText(getApplicationContext(), "Ad left application!", Toast.LENGTH_SHORT).show();
}
@Override
public void onAdOpened() {
super.onAdOpened();
}
});
ad.loadAd(adRequest);
任何人都可以帮我解决这个问题吗?
答案 0 :(得分:2)
像这样声明AdView,
firestore exports.noteCreated = functions.firestore
.document('note/{noteId}')
.onCreate(event => {
// Get an object representing the document
// e.g. {'name': 'Marie', 'age': 66}
console.log('New Note Created');
});
或者,我想你需要更换
<com.google.android.gms.ads.AdView
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:id="@+id/adView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
ads:adSize="BANNER"
ads:adUnitId="@string/banner_home_footer"
ads:loadAdOnCreate="true" >
